Log Dyno Horsepower CSV Dyno App DESCRIPTION

Measuring your car’s torque and horsepower has never been easier, now that you can do it with the help of your mobile device and this digital Dyno. You just need to open one of your datalog of a pull, and Log Dyno will do the rest.

You can use any CSV or MSL OBD datalog file that contains RPM data which is needed to measure Horsepower and Torque. You can also use SPEED data from GPS performance measurement devices such as VBOX.

From the torque curve, the app is also able to determine the optimal gear shift points to ensure maximum acceleration. This makes sure you know when to shift, so you always have the most possible power at the wheels.

Compare multiple measurements!

You can save each one of your Dyno measurements, and compare them, or just analyze them interactively.

What datalog files can be used?

● JB4
● MHD
● ProTool
● COBB
● MegaSquirt
● ProTool
● Bootmod3
● and any other CSV datalog with RPM data or GPS Speed

This is the easiest way to have your torque and horsepower measured with a virtual dyno using only your mobile phone and your datalog. You can see if your mods or tune work right away, and compare them.

★Log Dyno has been compared to multiple real life dyno sheets, and measurements were spot on, with multiple different vehicles★

How does it work?

#1. Datalog your vehicle
Take the datalog just like a dyno pull, in one given gear, from low rpm to high rpm. Try to avoid wheelspin as it can cause spikes in the graph.

#2. Set up your vehicle data

The dyno app requires some data about your vehicle. You’ll be asked to set values for the following:

● Car Name
● Weight
● Tank Capacity
● Tire Size
● DT%
● Drag Coefficient
● Frontal Area

#3. Share the results!

You can share your results right from the virtual dyno measurement page to basically any app or post it to any social network or email it. Of course, you can just save the results in your phone gallery too.

For more detailed information, scroll down to the bottom of the description and see the User’s Guide.

How accurate is the dyno measurement?

If you have set your vehicle data correctly, the results our dyno app gives will be the same as the results a real dyno will give you. Also, keep in mind that wheelspin may result in spikes in the graph. If you are unable to avoid it, you’ll still get accurate results, you just need to ignore the spikes.

The best thing about our dyno app is that you can see right away how your mods work after datalogging. Now, you don’t have to go to the dyno if you want to measure any small modification or just never had your car’s power measured. You can see right away how your mods or tune work after datalogging. You can dyno unlimited times and unlimited vehicles for the fraction of the price of a dyno measurement.

You have to set your car up, how much it weighs, its tire size, the gear ratios, and also what your car drag coefficient and frontal area are, which the app will help in determining.

Based on your car data and environmental values, the app calculates a torque and horsepower curve from the datalog, which you can analyze. The app also points out the peak values, and you will be able to see at what rpm you made the most torque and the most power.

Corrections:
● Uncorrected
● SAE J1349
● STD
● DIN 70020
● ISO 1585

Power Units:
● WHP
● BHP
● PS
● KW

Torque Units:
● LB-FT
● NM
At the wheels or at the crank

The app is widely used among N54 N55 and S55 Tuners with great results backed up by dyno runs.

You can datalog either via OBD or your piggyback tuner, all you need is a CSV file. You can also use a GPS device to datalog SPEED for measurement.

App REVIEWS

Anthony

Very comprehensive app,

Bee

Works great with CSV logs. Might have to rename titles for it to grab data. Works great for my R34 Haltech CSV logs and mates BMW 335i JB4 logs. Matches my own dyno results. VERY SIMILAR 411kw on dyno. shows 390-420kw on various street runs.
----------
Thanks for the feedback! If you are using OBD data then wheelspin and road conditions make a fairly big impact on readings. If you have a chance use GPS data from a logger for getting the most consistent results.

Ravinder

this app gives accurate reading for torque and horsepower. Just have to make sure that logs are smooth

david

First I want to say I actually really enjoy this app. However, after the update I lost the ability to read my logs from MHD and my vehicle settings were deleted. Was this common for other users? Is there a fix so I can change my review to 5 stars?
----------
I am sorry to hear you have lost your save data, haven't received reports of it though. You should still be able to read MHD logs, if your issue still persists please email me. Also you could make a backup of the SaveData file to yourself, you can always copy it over and pick up from there if you change devices and so on.

David

Easy way to test Modifications and the support is exactly you would hope to get from any developer! (But rarely do) Definitely Worth the Cost of the app.

Alex

Great app, very accurate compared to my real dyno results on multiple cars.

Rocket

Car info is saving now. One program i have to edit the csv first, with another it just loads em right up. Works great and Customer Support has been great!

Guest

User guide does not list what parameters you need to log other than rpm. *Edit finally found a good app that I can log rpm and tps with out any problems. This app works great for me and does everything I need it to. Would recommend
----------
Because you only need rpm, that's literally all you need to datalog. Timestamp is automatically added to every log. If you still don't understand something I am always available via email profisoftgames@gmail.com

Dan

Outstanding. This is the best kept secret for diy tuners. Simple app that gets the job done and has amazing customer service. I don't know how this hasn't been downloaded thousands of times yet.

Steve

Haven't uploaded a log yet but I stumbled on this app today and funny thing is, I have been trying to calculate shift points on an online shift point calculator with other dyno graphs that seem similar to my setup. I feel like this app will be much more effective using data from my car and I just got MHD for logging (mainly for gauges). With XHP and the ability to change shift points for each gear on the ZF8, this should be awesome especially when changing my setup (which I do a lot). I will make sure to update this review once I upload a log and verify everything!
----------
Thanks for the feedback, if you need any help just email me, profisoftgames@gmail.com

Oscar

Not working for me. I configured everything correctly and even double checked to All .csv files I used shows my car making almost 700hp when in reality my car makes around 310whp.
----------
Peak numbers are only a very small part of the whole picture, if the measurement curve has a spike, it can throw off peak readings. Email me your measurement curve screenshot so I can help you. I have met 100s of cases with wrong results and all of them were because of user error. profisoftgames@gmail.com

Mic

Works well, close results to other software and actual dyno runs. Developer knowledgeable and very helpful. Very glad I bought this.

christia..

I think it reads low. I have an actual dyno sheet and the numbers for this are off about 20 hp Edit: I realized i did not put in the right correction factor. Once i put the right correction factor it was in line with where it should be. Worth the money. Also gives you shift points to make the most out of the powerband.
----------
Thank you for your feedback. When comparing results always make sure to use the same correction factors. Calculated shift points come in very handy when you want to maximize acceleration.

Guest

If the details are filled accurately and logs are done properly it is suprisingly accurate and lined up perfectly with my estimated hp based off my 1/4 mile trap speed.
----------
Thank you for your feedback, also make sure to use the same correction factors when comparing measurements. In the US STD and SAE are the most commonly used ones.

Guest

I uploaded a 5th gear pull .csv file. I entered all the information in very carefully making sure everything from vurb weight, gear ratios, fuel etc... Were accurate. The app is saying my 2015 BMW M4 with OEM turbos is putting down 800 whp and 4000 ft/lb of torque. Don't waste your money on this garbage app...
----------
There is obviously something wrong with either the log or have you selected 5th gear for measurement gear? Why don’t you email me at profisoftgames@gmail.com ? I have helped everybody personally who had difficulties using the app.

Guest

Pretty accurate if you input the correct info.

Guest

very cool app once you get everything dialed in. developer is extremely helpful and quick to respond. highly recommend

Guest

App works as long as the file is saved correctly and you don't have anything logged that conflicts with what the app is looking for. Good customer service though, getting back to me and figuring out what was wrong with my log to make it work.
----------
Please contact me at profisoftgames@gmail.com and I will be happy to assits you, and help you figure the issue out. Log Dyno expects a certain data, and data format, column name, which is set up for the most commonly used datalogging softwares. The RPM data column header name should contain "rpm" and the timestamp header name should contain "time".

Guest

It's pretty accurate. Developer is very approachable and knows his app extremely well. A+
----------
Thank you for your feedback. Remember, you can contact me at any time if you have any further questions.

Guest

Accurate when u put the right settings owner very helpfull if ur lost just send an email
